| The first step is to set up the links as per the manual, then see if you get equal travel negative and positive pitch, +12 _ -12. If you have great, if not you need to adjust the three swash links till you get equal travel up and down. When you have acheived this then check at centre stick, you have 50% in 50% out on your radio and then check your pitch is around 0, Then adjust for zero degrees with the pitch rods, till both blades have the same pitch. Then adjust your curves in the radio to give you the pitch you require for your flying. Have a search on the web for set up videos for the trex 500, they are very good.
The reason you are probably not getting the correct pitch values is because there are 3 different types of servo's spec'd for the trex 500 and they all have the output arms in different places therefore the pushrod lengths will be different for each servo. The manufacturer gives a ball park figure to get you going you have to work from there. Sometimes the are spot on sometimes they are a bit out.
Good luck
